Statistical features extracted from the Gray Level Co-occurrence Matrix (GLCM) of liquid crystal textures are used to investigate the phase transition temperatures of nematic liquid crystals p – n Alkyl benzoic acids (nBA) where n = 8,9 and10. Textures of compounds are recorded as a function of temperature using Polar…
This study reports the design and synthesis of a series of D–A copolymers alternating benzothiadiazole and benzotriazole acceptors to a donor co-unit, and investigates their photovoltaic properties in bulk heterojunction solar cells with PC71BM. Successive modifications to the copolymers are carried out, passing from…
A 2D MOF with the secondary building unit [Co3(CTC)6(Py)2(OH)2] is synthesized using the sodium salt of a flexible ligand, cis,cis-cyclohexane-1,3,5-tricarboxylate (Na-CTC), and a cobalt trimer ([Co3O(CH3COO)6(Py)3]·ClO4). Structural analysis shows that the complex crystallizes in the monoclinic space group P21/n and…
A well-defined PNIPAM-PS star block copolymer with a porphyrin core was synthesized by a reversible addition–fragmentation chain-transfer (RAFT) process, and was found to efficiently capture and decompose environmentally toxic organic materials such as benzene, toluene, ethylbenzene, and xylene (BTEX) in water under U…
Abstract—It is well known that additional space harmonics in the air-gap magnetomotive force (MMF) distribution of the concentrated non-overlapping windings (CW) cause additional losses in the machine. This is especially so for machines used for traction applications where the machine requires to operate over its rate…
We report a simple colorimetric method based on a water soluble polymer (WSP) for the sensitive and selective detection of cyanide in a biological solution. The WSPs were prepared from a radical polymerization of a methacrylate with a cyanide chemosensor moiety based on a coumarin–dicyano-vinyl derivative motif, and t…
A fail-proof synthetic strategy has been developed for a multiply twinned dumbbell-shaped Rh@Pt nanostructure, which exhibits a superior electrocatalytic activity for methanol oxidation reaction. The unusually high electrocatalytic activity has been attributed to the synergistic effects of crystal twinning and core-sh…
With the explosive growth in the synthesis of coordination polymers, several systems are now available which exhibit transformation without losing single crystallinity. Among different types of single-crystal-to-single-crystal (SC-SC) transformations, those that involve the first coordination sphere of the metal cente…
According to recent advances in nanotechnology, various nano-sized formulations have been designed for the application in biomedical fields, including diagnosis, drug delivery, and therapeutics. The nanotechnology-based formulations have a great merit in the design of multifunctional platform for the biomedical applic…
A series of narrow band gap donor–acceptor type conjugated copolymers based on 2,6-linked anthracene derivatives are synthesized via Suzuki copolymerization. The resulting copolymers typically exhibit dual absorption characteristics in both solution and as thin films with optical band gaps in the range of 1.85–2.13 eV…
A revolutionary probe was constructed by conjugating Cy5 on a graphene oxide sheet. The fluorescence was quenched owing to its proximity to graphene oxide in normal circumstances, but lit on arriving at the tumor site. Both in vitro and in vivo studies demonstrated that the probe exhibits great potential for tumor dia…
A magnetically separable catalyst was synthesized via a carbodiimide activation process with β-cyclodextrin functionalized by core-shell nanoparticles (Fe3O4/SiO2/CM-β-CD). The catalyst presented high activity for selective oxidation of various alcohols with NaOCl as oxidant and water only as the solvent. A substrate-…
The so called v / G criterion defines a critical value Γ0 crit of the ratio Γ of the pulling rate v over the thermal gradient G at the melt-solid/interface. For a ratio larger than this critical value, the crystal is vacancy-rich while for values below the critical value, the crystal is self-interstitial-rich. When th…
A novel system for the recovery of reinforcing fibers from fiber reinforced plastics (FRP) and their recycling technology has been developed on the basis of the thermal activation of semiconductors (TASC). TASC is our new technology characterized by the use of oxidative properties of defect electrons (i.e., hole) of s…
Near-field dipolar plasmon interactions of multiple infrared antenna structures in the strong coupling limit are studied using scattering-type scanning near-field optical microscope (s-SNOM) and theoretical finite-difference time-domain (FDTD) calculations. We monitor in real-space the evolution of plasmon dipolar mod…
Large-scale uniform ternary ZnIn2S4 nanosheet array films have been grown on indium-tin oxide (ITO) glass substrates effectively by a simple direct elemental reaction route. Inorganic–organic bulk heterojunction photovoltaic devices were fabricated with ZnIn2S4 film as an electron acceptor and poly (2-methoxy-5-(2/-et…
We present the numerical simulation, using the finite difference time domain (FDTD) method, of the radiative heat transfer between two thin SiC slabs. We aim to explore the ability of the FDTD method to reproduce the analytical results for the Surface Phonon Polariton (SPhP) assisted near field radiative energy transf…
An electrochemiluminescence (ECL) immunosensor for HepG2 cells (human liver hepatocellular carcinoma cells) was fabricated based on CdS-capped TiO2 hybrid nanoparticles. The CdS-capped TiO2 was obtained by immersing TiO2 nanoparticles into separate Cd2+ and S2− solutions successively 10 times. The hybrid nanoparticles…
The concept of thermoregulated phase-transfer catalysis (TRPTC) for an aqueous–organic biphasic system was applied in Cu(II)-mediated atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA). Herein, activators generated by electron transfer (AGET) ATRP was used to establish the TRPTC ATRP system using…
In this report, flower-like Au nanochains were facilely prepared by a one-step synthesis with the assistance of caffeine as a structure directing and weak stabilizing agent. It was found that the reaction temperature and the ratio of [caffeine]/[HAuCl4] were the key factors during the synthesis process, and their grow…
